My watch was 3 minutes slow at 5 pm on Tuesday and it was 5 minutes fast at 11 pm on Wednesday. When did it give correct time?

1. Wednesday 4 : 15 am
2. Wednesday 7 : 30 am
3. Tuesday 3 : 45 pm
4. None of these

We know that ,
Time from 5 pm Tuesday to 11 pm Wednesday = 30 hours

∴ Correct time is 11 hours 15 minutes after 5 pm. = 4 : 15 am on Wednesday.
Thus , required correct time is 4 : 15 am on Wednesday.
